SNAPSHOTCOPY

The SNAPSHOTCOPY function behaves like SNAPSHOT but does not consume the elements of the stack, instead it produces WarpScript code which will regenerate the stack as it was before the call and pushes this code on top of the stack.

Note that some types of objects created by third party functions may not be serializable, SNAPSHOTCOPY will emit a STRING of the form UNSUPPORTED: class xxx when such a type is encountered.
